Step-by-step explanation:
14) percentage of increase
% of increase = (new - original)/original × 100
= (40 - 35)/35 × 100
= 5/35 × 100
= 14.285% = 14% increase
15) percentage of decrease
% of decrease = (original - new)/original × 100
= (16 - 10)/16 × 100
= 6/16 × 100
= 37.5% = 38% decrease
16) percentage of increase
% of increase = (new - original)/original × 100
= (73 - 27)/27 × 100
= 46/27 × 100
= 170.37% = 170% increase
17) percentage of decrease
% of decrease = (original - new)/original × 100
= (92 - 21)/21 × 100
= 71/21 × 100
= 338.10% = 338% decrease
18) percentage of decrease
% of decrease = (original - new)/original × 100
= (21.2 - 10.8)/21.2 × 100
= 10.4/21.2 × 100
= 49.06% = 49% decrease
19) percentage of increase
% of increase = (new - original)/original × 100
= (25 - 11)/11 × 100
= 14/11 × 100
= 127.27% = 127% increase
20) percentage of increase
% of increase = (new - original)/original × 100
(76 - 68)/68 × 100
8/68 × 100 = 11.77% = 12%
21) percentage of increase
% of increase = (new - original)/original × 100
= (40 - 21)/21 × 100
= 19/21 × 100
= 90.47% =90%
22) New car = AED 45,500
Used car = x
New car = (25% of x) + x
45,500 = (25x/100) + x
45,500 = (25x + 100x)/100
45,500 = 125x/100
45,500 × 100 = 125x
4,550,000 = 125x
x = 4,550,000/125 = 36,000
x = AED 36,000
